The Purchasing Decision, Solved

What to buy. When to buy. How much.

One number per SKU — computed from sales, inventory, seasonality, bundles, variants and supplier lead times.

Step 1

What to Buy

Every SKU that will run out inside your lead time — surfaced automatically.

Step 2

When to Buy

Timed to your supplier lead time so replenishment lands before you sell out.

Step 3

How Much to Buy

Coverage math that reads velocity, seasonality, bundles and open POs — no guesswork.

Every owner is asking the same four questions.

You are here because at least one of them is keeping you up at night.

Q1

What should I buy next?

The exact SKUs to reorder this week — quantities timed to your supplier lead time.

Q2

Am I buying too much?

Slow-moving stock, excess coverage and cash trapped — surfaced before you write the next PO.

Q3

Can I trust my inventory?

Bundles, kits, variants and multi-location stock reconciled against live Shopify.

Q4

Can I still manage this manually?

Growing SKUs, suppliers and complexity — kept under control from one screen.

Here are the products needing attention.
Here is what we recommend you order.

This is the screen most SupplyWatch merchants open on Monday morning.

Cash Trapped in Inventory

How much cash is trapped in your stock?

Every unit on the shelf is working capital you have already spent. Overstock and dead stock quietly tie up cash you could be using to restock bestsellers — the classic cash-flow trap for growing Shopify stores. SupplyWatch shows exactly how much cash is tied up in slow-moving and excess inventory, and what to reorder instead so your money keeps moving.

  • Inventory value / cash tied up
    The total working capital locked in stock right now — valued by variant and location so you can see where your money actually sits.
  • Dead stock & slow-moving inventory
    SKUs carrying weeks or months of excess coverage — trapped cash that could restock a bestseller instead of gathering dust.
  • Overstock & carrying cost
    Where you have over-ordered, plus what to buy this week ranked by urgency and supplier lead time — free the cash, keep the shelves right.

Free up the cash tied up in dead stock — and put it into inventory that actually sells.

Reorder qty for the kit is limited by Protein Powder — SupplyWatch orders exactly enough of each component to unlock the bundle.
Bundle-Aware

Selling bundles, kits or variants?
Purchasing gets that much harder.

SupplyWatch decomposes every bundle into components. When a bundle sells, each component is attributed. Reorders cover the bottleneck component — not just the hero SKU.

  • Auto component detection for kits, sets and variant combos — no manual mapping.
  • Bundle sales attributed to every component so velocity reflects real demand.
  • Reorder to unlock the bundle, not just the bestseller inside it.
Inventory Accuracy

Can you trust your inventory numbers?

If your inventory data is wrong, how can you know what to buy? Every reorder, every purchase order, every “are we about to run out?” depends on one thing: accurate stock counts. SupplyWatch keeps your inventory accurate in real time and reconciles every stock movement — so purchasing decisions rest on numbers you can trust, not a spreadsheet that drifted three weeks ago.

  • Real-time inventory tracking — live Shopify sync over official webhooks. Fulfil, receive or adjust and your stock count updates instantly. No overnight batch, no stale numbers.
  • Inventory reconciliation you can audit — a ledger-based timeline logs every sale, PO receipt, stock-take and manual adjustment as a dated event. One source of truth across your entire catalogue.
  • Catch shrinkage & stock discrepancies — cycle counts and stock-takes surface miscounts, shrinkage and drift, then correct them before a wrong number skews your next purchase order.

Accurate inventory in, smart purchasing out. Wrong numbers make every buying decision a guess.
